  • Motor drive device
    Patent number: 8111027
    Abstract: The present motor control device detects from the speed of a motor and a current driving the motor that the motor is overloaded, and exerts control to set a target torque based on the detected overload state of the motor to cause the motor to output a maximal torque that the motor can output, intermittently within a preset allowable speed range. If the motor is overloaded, the motor's output torque is not decreased and a drive circuit can also be protected.

  • Data transfer unit, data transmission device, data receiving device, and control method
    Publication number: 20110309868
    Abstract: A transmission LSI calculates a buffer usage rate in accordance with data stored in a buffer in a transmission data processing unit and determines, in accordance with the calculated buffer usage rate, the number of signal lines that perform a phase readjustment and the timing thereof. Then, the transmission LSI and a receiving LSI perform a phase adjustment using some of the signal lines and continues a data transfer using the rest of the signal lines. Accordingly, it is possible to maintain the optimum phase of a clock without delaying the data transfer.
